If in a population of size 'N' the birth rate is represented as 'b' and the death rate as 'd' the increases or decreases in 'N' during a unit time period 't' will be:
The equation given above can also be represented as:
What does 'r' represent? Write anyone significance of calculating 'r' for any population.
The 'r' is called the 'intrinsic rate of natural increase' 'r' is a very important parameter chosen for assessing impacts of any biotic or abiotic factor on population growth.
